My three neons (Bernard, Bootle and Bumtrinket) have recently started indulging in bouts of chasing each other. The chasing seems to consist of very small circles or figure eights round each other but *really* fast and for minutes at a time, or they dart straight at each other, only veering off at the last possible nano-second. Bernard and Bootle especially do this; Bumtrinket's not quite as vigorous, bless him.
But are they quarrelsome, amorous or simply playing 'chicken'?
